If the linkage console uses a low frequency circuit, a common wire resistance is usually used, with high power, low current noise, high temperature resistance, but the volume is large. Typical winding resistors are typically used as a low frequency circuit or a current limiting resistor, a voltage distribution resistor, a bias resistor or a high power tube bias resistor. High precision wire winding resistors are used in high-precision attenuators, resistance boxes, computers, and various precision electronics.
The resistance of the linkage console is a current limiting component that limits the amount of current flowing through the resistor connected to the circuit when connected to the circuit. If the resistance of the resistor is close to 0 ohms, there is no current flowing through the resistor, and the circuit connected in series with the resistor is short-circuited, and the current is infinite. If the resistance is unlimited or the resistance is large, the loop connected in series with the resistor can be considered a zero current opening. The electrically used electrical resistance is between two extremes, with a specific resistance and can pass through a certain current, but the current is not as large as the short circuit. The restrictive limitation of the resistor is similar to the effect of limiting the water flow by a small diameter tube between the two large diameter tubes. The voltage distribution effectively reduces the input voltage of the instrument, R2 is the current limit, and the voltage distribution can be connected in series with the target device because the current of the instrument can be controlled by the size of R2.
